I need help with a math question!!

[From: ] [author: ] [Date: 12-03-11] [Hit: ]
.Thank you!!!= 7 x (.3) + 0.......
I am trying to solve for x in the equation:

((7*2^x)+3)/(11-(5*2^x))

can you please help me?... I have tried to get the variables on one side than factor out a 2^x for it doesn't work..

Thank you!!!

((7*2^x)+3)/(11-(5*2^x))

(7*(2^x) + 3) / [11-(5*2^x)]



7 * 2^x + 3 = 7x log 2 + log 3

= 7 x (.3) + 0.47

= 2.1 x + .47 ---------------- 1



11-(5*2^x) = log 11 - 5x log 2

= 1.04 - 5x (.3)

= 1.04 - 1.5 x --------------------- 2


dividing 1 by 2

2.1 x + .47
---------------------
1.04 - 1.5 x


PS = no further simplification is possible.

as q is not equation, value of x can not be found.
